Test Project Results
The CIDOC Correlation test project
has brought results on both, the theoretical side and the practical
side. On the theoretical side a series of data formats were compared
with the CIDOC CRM and mapped to the CRM.
Those were:
Those mappings led to the extension proposal
of the CRM at the Agios Pavlos meeting, which will soon be submitted
to the CRM Special Interest Group. The mappings confirmed the validity
of the CRM approach, as the Agios Pavlos extensions need not touch
any of the basic constructs of the CRM. In its extended form, the
CRM provides a virtually complete coverage of museum and archival
notions relevant for information exchange. (For more details see
the definitions of the scope of the CRM).
On the practical side, the CRM has been the logical base for the SPECTRUM
XML DTD currently under test at CIMI, and the development of the Musinfo
project in Geneva, building a web based information system used by Geneva
City's museums. It has influenced the ABC
Harmony Data Model Version 2 and it is being used in the RLG's
Cultural Materials Initiative. Other groups are currently using the CRM as
intellectual guide for DTD definition, e.g. at the Germanische
Nationalmuseum in Nuremberg.
Further, in the framework of the Harmony + CIMI Collaboration: Interoperability and metadata vocabularies, the extended CRM has been base for data
transfer experiments from museum data of 4 organisations to the CRM (National
Museum of Denmark, AMOL, RLG, The
John Clayton Herbarium). ICS-FORTH is
assisting Harmony in
this collaboration with respect to the use of the CRM: This work implied the
definition a simple data transport DTD for CRM instances and a simple XSL presentation
form which renders CRM instances fairly readable, and data
between the different data structures.
Finally, a sample data set from the Science Museum London has been transformed
automatically from Microsoft Word format to the CRM.
Further results of these data
transformation tests are being published on this site. From the first experiences,
we can conclude, that the CRM is a perfect mechanism to bring museum data into
a common, highly analytical form without loss of information, for data transport
and data merging.
We hope, that these tests will encourage the widest possible use of the
CRM as a solution for semantic interoperability in the community.
